ARTHUR BOYCE, OF ST. LOUIS, MISSOURI.-

BOILER-FURNACE AND STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 519,419, dated May 8,1894.

Application filed July 10,1 893.

To all whom it may concern: y

Beit known that I, ARTHUR Boven, of the city of St. Louis, State ofMissouri, have invented certain new and useful Improvements in aCombined Smokeless Boiler-Furnace and Steam-Generator, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention relates. to combined smokeless boiler furnacesand -steamgenerators, and consists in the novel arrangement and com# bination ofparts, as will be more fully hereinafter described. v

In the drawings: Figure 1 is a longitudinal Vertical section taken toone side of the boiler. Fig. 2 is a vertical transverse section taken onthe line :1o-a: of Fig. '11. Fig. 3 is a front end elevation. 4

My invention has for its object the saving of fuel and also increasingthe heating capacity of the boiler, as well as the successful burning ofthe smoke and gases generated therein, the same being attended with nogreater expense of construction than the orvided with flanges or sideplates 2 which rest on brick walls 3 for supporting the same.

4 indicates a smoke passage through which all the smoke and products ofcombustion and gases which are not consumed, in a manner as will be morefully hereinafter described, find exit to the atmosphere.

5 indicates an end brick wall which is located to the rear end of theboiler 1 and a distance therefrom whereby the smoke-passage 6 is formed.Located in this smoke-passage 6 is a brick-damper 7 the same beingpivotally mounted as illustrated in the drawings and adapted to beoperated by a handle 8. By this damper a direct draft can be formed or acircumlocutory draft, as will be more fully hereinafter described. f

Located below the brick wall 5 is a sootchamber 9 the same beingprovided with a soot-door 10 as is illustrated in Fig. 1.

l1 indicates an ash-pit which is located be- Serial No. 479,984. (Nomodel.)

low the grate bars 12 which are of the usual construction.

13 indicates a fire box in which the fuel is placed and 14 indicates thedoor thereof.

15 indicates a bridge wall which is located in the rear of the' ash-pit1l 'and the re-box 13, the same being provided with an inclined surface16.

17 indicates a stratum of dirt which is provided on its top surface witha layer of brick 18.

Located below the boiler 1 is a Water receptacle 19 which is curvilinearin cross-section. ceptacle 19 is comparatively thin as relates to itslength andwidtlnthe same being preferably greater in length than theboiler 1 and of greater width than the diameter of the boiler. (SeeFigs. 1 and 2 for illustration.) Said receptacle 19 is constructed ofboiler (See Fig. 2 for illustration.) Said remetal, cast iron, or anysuitable material, and

one object is to increase the heating surface of the boiler and anotheris to act as a means for consuming the smoke as will be more fullyhereinafter described.

20 indicates water legs, the lower ends of which are incommunicationwith the receptacle 19 and the upper ends with the boiler l'at the side thereof as can be seen in Fig. 2. Said Water 7legs aresecured to the boiler 1 and receptacle 19 in any suitable and mechanicalmanner.

21 indicates one or a series of water legs which are in communicationwith the receptacle 19 and are secured directly beneath the boiler 1 andare in communication therewith. Said legs have an additional function ofconveying mud or sediment which accumulates in the boiler 1 into the thereceptacle 19.

The receptacle 19 as vbefore stated, is located beneath the boilerl'leaving a smoke passage 22 between said boiler and recepta- IOO with acourse of tire brick 29,. and superposedA:`

upon said plate 28 is a horizontal fire brick wall 30 which extends fromsaid `front plate 28 to the end of the boiler lfThe front platel 28 isprovided with a series of openings 31 which are provided with dampers32; said openings31 act as airpassages for thead-:i

mission of air into the igniting chamber 211.

33 indicates flue doors,which arejo'f the oi dinary construction,through which admission may be effected to the lues of the boiler.

The `operation ofthe furnace isasfollows:

Y The fuel is vplaeedlintlie fire box y13 and when ignited'bytheoperator the smoke ,and .products of combustion .pass backward beneaththe' receptacle 19throu`gh the throat 26.31111 channel 23 as indicatedby arrowsaudiil the damper `'2" is closed the said smoke and .productsof combustion is4 diverted 4and passes backward in an opposite directionthrough the passage or channel 22` located above the receptacleli) and`when the same getsto the igniting chamber2ltlying above the fire box 13it is presumedthatq the flame passing upwardlythroughthe. openings25willvconsume or partially consume. `said` smokev and products ofcombustion. The remaining smoke and products of combustion `will passthrough the iiues of the boiler and, out "throug'hklthe smokepassage 4.`Vihen it is desired to create a straight draft fthefoperator `opens thevalve or the damper7 and the smokeor products ofcombustionwill passdirectly through the passage or channel23 "Yup through ithe smokepassage `6 and `out at the 4smoke l.passage L As before stated thelegati/)1l `actas a conductor or conveyerfor the mud and sedi!` ment.which may accumulatein ,the boiler 1. The mud and `sediment whichpasses into the receptacle 19 `will gravitate towardthe `edges I of thesame, fcr the reason thatysaidreceptacle inclines downwardlyfrom theconte;` as illustrated in Fig. 2 and said mud andsediment may bedischarged through the discharge pipe 34: provided with a valve 36`which* is secured to the under side of the receptacle 19 l. and incommunicationtherewith asillustrated in ig.`l. l The object of fillingin` the dirtl( is to completely till up all the unnecessary space` sothatiall, the heattmay be.y utilized. `By employing the receptacle 19 itcan be `readily perceived that the heating surface of the boiler is verymuch increased.

35 indicates a stone foundation or base of Iwhichthehereinbeforetdescribed mechanism is preferably constructed andsuperposed.

From the foregoing description it can be `readily perceived `thatfafurnace of the above `construction consumes or partially consumes thesmoke and products of combustion, that the same may .begvery cheaplyconstructed, a

`large percentage, ot? the heat generated is utilized; and the heatingsurface of the boiler is materially increased. t t n `Havingfully Qcr'bed myinvention ,what I claim `is-L` h 1. smokelessboiler,furnacecomprising a boi1`er,`a water reeptaclelocated beneath theboilerw andvhaving' communication" therewith and providedwith a passage,a fire-*boxe or chaniberloicated` below thepassage inthe waterreceptacle, an igniting chamber located above thepassage inthewaterreceptaclaan air passage located belowthe water receptaclel andproviding communication for the smoke and products of combustion'fromthe fire-box to the igniting chamber, adamper located inthe rear ofthelire-bort` wherebythe flow of smoke` and products of combustion isdeflected n. and directed,` and a mud exhaust pipelocatedintherear ofthe receptacle, a1'- ranged and combined in the mannerset` forth forthepurposes stated. 2- A smokeless boiler furnace consisting 0f a boilersuch` as n 1,l areceptacle suchwas 19 curvilinear in croslssection,water legs such as 20 `and21wfor aor/ding. communication between saidboiler and receptacle, a Iirechamber located beneath said" receptaclm'an`igniting chamber` located above the samepa passage formed in saidreceptacle for aording communicationk between said l igniting chamberand iirechatnber,` a mud exhaust pipe 34 secured to the rear ofsaidreceptacle, a damper 7, a front plate 28 provided with a series of airpassages 31and dampers 32, substantially as set forth.

iIn testimony whereof `I affix my signature in presenoeof twowitnesses.
